ISO 11503

Kesternich testing simulates acid rain or industrial chemical exposure  to evaluate the relative corrosion resistance of the coating, substrate, or part itself.  Parts or panels are placed inside a specially designed chamber and are exposed to SO2  and humidity before being evaluated for resistance to corrosion.  The following standard used in this type of test.

ISO 11503 Test Standard deals with the testing of paints, varnishes and related products. Specifies a test method for determining under standard conditions the resistance of a single coat or a multi-coat system of paint or related material in intermittent water condensation.

ASTM D1748

Test Method for Rust Protection by Metal Preservatives in a Humidity Cabinet

This standard specifies a test method for evaluating the rust preventative properties of metal preservatives under conditions of high humidity. Steel panels are prepared to a prescribed surface finish, dipped in the test oil, allowed to drain. They are then suspended in a special design of humidity chamber (which must meet the requirements of Military Specification JAN-H-792) where they are exposed to a temperature of 48.9C (120F) and a high (unspecified) relative humidity. This climate is maintained under constant steady state conditions. The test duration is variable.

Ascott do not currently manufacture a corrosion test chamber for compliance with this test method.
